G'day, I've fixed a potentially risky situation in Lusca relating to the initialisation of the storeIOState cbdata type. Each storedir has a different idea of how the allocation should be free()'ed.
The relevant commit in Lusca is r14208 - http://code.google.com/p/lusca-cache/source/detail?r=14208 . I'd like this approach to be included in Squid-2.HEAD and backported to Squid-2.7 / Squid-2.6. Thanks, adrian
